THOMAS B. COOPER AND FERDINAND F. ROB, OF BALTIMORE, MARYLAND.

FLUSH-VALVE.

Specification of Letters Patent.

Patented June 22, 1915.

Application filed May 18, 1914. Serial no. 839,227.

To all whom it may concern Be it known that we, THOMAS B. Coornn and FERDINAND F. Ron, citizens of the United States, residing at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Flush- Valves, of which the following is a specification.

This invention relates to flushing valves for closets and has special reference to an anti-freezing valve for outdoor closets in cold climates.

The principal object of this invention is to provide an improved and simplified valve of this character wherein the depression of the closet seat will open a valve to supply water to a flushing tank and at the same time close off the closet so that when the seat rises the communication with the supply pipe is closed off and communication between the tank and the closet opened.

Another object is the provision of means for bleeding all water out of the valve after the flushing operation.

With the above and other objects in view the invention consists in general of certain novel details of construction and combination of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and Figure 1 is a side elevation of a closet showing a valve con: structed in accordance with this invention applied thereto. Fig. 2 is a vertical section taken through such a valve showing the valve in the position assumed when communication is opened between the inlet or sup ply pipe and the tank. Fig. 3 is a section through the casing on the line 33 of Fig. 6. Fig. 4 is a detail plan view showing the relation of the seat hinge to the top of the valve. Fig. 5 is a section on the line 5 -5 of Fig. 2. Fig. 6 is a section on the line In the present embodiment of the invention as illustrated in the accompanying drawings there is disclosed a closet 10 provided with a seat 11 and from this closet extends the soil pipe 12. Extending through the ground sufliciently far below the upper surface to prevent freezing is a water supply pipe 13. This water supply pipe 13 is connected by a nipple 14 with the lower end of a lower valve body 15. This lower valve body 15 is located sufiiciently far below the level of the ground to prevent freezing and from the lower valve body extends upward a pipe connected by means of a pipe 21, with a tank 22 sufiiciently elevated to give proper flushing action. The branch 18 furthermore carries a bracket 23 and to this bracket 23 is hinged a seat support 24 having rearwardly extending fork arms 25 one of which carries a weight 26 so arranged as to normally hold the seat 11 slightly raised. This weight, in itself, is not suflicient to raise the seat unassisted but the means for effecting this lifting of the seat will be further disclosed.

The upper end of the body 17 is closed by a cap 28 and through this cap extends a slidable valve stem 29 which carries on its lower end a valve disk 30 arranged to seat in a valve seat 31 formed between the branches 18 and 20. Just below the branch 20 there is provided within the body 17 an interior annular shoulder 32 whereon rests the lower end of a spring 33, the upper end of this spring bearing against the valve disk 30 so that this spring holds all the movable parts of the valve normally raised and assists said weight in holding the seat raised. In order that the spring 33 shall assist the weight 26 the upper body 17 is provided with a bracket 34 whereon is pivoted a lever 35 carrying at one end a set screw or adjustable screw 36 the point of which engages the upper end of the stem 29. The other end of this lever 35 is provided with a cross bar 37 the ends of which rest on the arms 25 so that as these arms are pivoted on the bracket 23 the lever 35 will be rocked in one direction or the other as will readily be apparent from inspection of the drawings.

The stem 29 is prolonged below the valve disk 30 and is provided at its lower end with a suitable socket 38 for the reception of the upper end of a rod 39, the rod being held in the socket by a pin 40. This rod extends downward to a point within the lower valve casing 15. Within this lower valve casing 15 there is provided an annular shoulder 41 whereon rests a packing washer 42. A sleeve 43 is threaded into the casing 15 and has a shouldered portion resting against the washer 42. Furthermore this sleeve is provided with radial guide screws 44 extending therein. a

The upper part of the casing 15 into which the pipe 16 is screwed is grooved as at 45 and leading from this grooved portion to a point adjacent the top of the member 43 are slots 46 forming fluid passages. Extending laterally from the member 15 is a bleeder extension 47 which opens into the valve seat 48 inwardly and is connected outwardly by a pipe49 to the waste pipe 12. At 50 is a valve which is adapted to seat in the valve seat 48 when depressed and which is provided with a socket 51 whereto the lower end,

of the rod 39 is secured bya pin 52. Extending downwardly from the valve 50 is a valve stem 53 which passes through the member 43, being guided therein by the screws 44. On the lower end of this stem is a valve disk 54 which is held in position by a nut 55.

In operation the device works as follows: When the seat is depressed the valve'disk 30 closes and thus cuts 011 all communication between the supply pipe and closet and the tank and closet. At the same time the valve 54 opens so that communication is established between the upper and lower ends of the casing 15. The water then flows up through the casing 15, connecting pipe 16, casing 17, pipe 21 to the tank 22. At

this time no water can escape through the bleeder 47 on account of its inner end being closed by the valve 50. lVhen the seat 11 rises then the spring 33 lifts the parts to the position shown in Fig. 1 whereupon the valve disk 30 is raised off the valve seat 31 upper part of the apparatus to freeze and prevent operation. Having thus described the invention,What is claimed as new, is

In a device of the kind described, a valve body including a pair of lateral extensions, said body being provided with a valve seat between said extensions, a cap closing the upper end of said body and provided with a centrally disposed opening, a valve stem slidably mounted in said opening, a valve 7 disk carried on said stem and adapted for seating on said seat, a lever pivotally mounted on one of said lateral extensions, a bracket extending upward from said body, a second lever pivoted to said bracket and extending over the upper end of said stem, said second lever having slidable connection at one end with the first lever, and an adjusting screw extending through the second lever and engaging the upper end of said stem.

In testimony whereof we afiix our signatures in presence of two witnesses.
